In the last decade, new technologies have transformed all stages of highway construction as more industry stakeholders have begun incorporating new technologies into their daily construction activities.

The TRB National Cooperative Highway Research Program's NCHRP Synthesis 578: Use of Unmanned Aerial Systems for Highway Construction documents the use of Unmanned Aircraft Systems (UAS) by state departments of transportation (DOTs) during highway construction, identifies potential benefits and obstacles DOTs face when implementing UAS in highway construction projects, and identifies information gaps to be filled that could enable state DOTs to enhance the benefits of UAS for construction-related operations.
